Exhaust noise limit!
Discussion
Has anything changed on this? I read a statement from 2017 where the police state 80dB. https://www.essex.police.uk/getmedia/5a4aaf2f-105f...
I've just made an exhaust for my car where the engine is non standard (basically, its a hot rod now) so where does the law stand given its not manufacturers standard engine let alone exhaust?

What matters is that the car does not make any more racket than it did from the factory. If you don't want to comply with that then you need to put it through a full IVA/SVA or whatever test.
Unless the car is tested properly with a sound meter, it's then up to the ears of the person listening to it and - such is life - your version of loud will be different from mine, which will be different from the person who's moaning about it.Edited by herewego on Monday 12th November 11:45

For which the limit is 99db to the following standard:"Position the vehicle within the authorised test area. With the sound meter horizontal, set the microphone height so that it is at the height of the exhaust outlet or 200mm from the ground, whichever is higher.
a. At an angle of 45 degrees to the exhaust outlet in the direction which gives the greatest distance between it and the vehicle contour
b. At a distance of 500mm from the exhaust outlet.
With the vehicle at normal operating temperature, run the engine at 3⁄4 of its ‘maximum power’ speed, and note the sound level reading obtained."
